CORBA 2.6.1 Programmer's Guide for C++

The register_file_number() method in NSDEFw_GCF::Client, however, may be useful in server wrappers that issue nowait Pathsend requests
without the use of a jacket procedure. This method makes a file number returned by a Pathsend call available to the NonStop CORBA pthread
mechanism for I/O completions.
TCP/IP Socket Event Handlers and Event-Handler Users (Classes Fw_Event,
Fw_Sock_Client_EH, Fw_Sock_Server_EH, and Fw_Sock_Listener_EH)
The classes in the header file sockeh.h enable client, server, and listener event handlers to use the TCP/IP socket interfaces. These classes
provide:
An abstraction of a socket address (class Fw_Sock_Address)
A socket client event handler (class Fw_Sock_Client_EH) that implements Fw_Client_EH using the socket address abstraction
A socket listener event handler (class Fw_Sock_Listener_EH) that implements Fw_Listener_EH using the socket address abstraction
A socket server event handler (class Fw_Sock_Server_EH) that implements Fw_Server_EH using the socket address abstraction
A get/put recycling factory
